UNITE STATES PATENT OFFICE.

WILLIS E. MOORE, OF THORNTOVVN, INDIANA.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 254,360, dated February28, 1882.

Application filed December 6, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIS E. MOORE, a citizen ofthe United States,residing atThorntown, in the county of Boone and State of Indiana, haveinvented certain new and useful Improvements in Ventilators; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 oft-he drawings is a sectional view of my invention, showingthe ventilating-pipes extended; and Fig. 2 is a similar view with thepipes drawn down wilhin each other.

The present invention has relation to certain new and usefulimprovements in ventilatingdwellings; and it consists in the details ofconstruction substantially as shown in the drawings and hereinafterdescribed.

In the accompanying drawings, A represents the upper portion of ahouseor dwelling, ithin which is located a pipe, B, which may by suitablebranch pipes extend to the several rooms or compartments thereof. Thispipe B is stationary and extends up through the roof of the dwelling, asshown, and has connected to it at its upper end a suitable pulley, a,over which passes a cord or chain, b. This cord or chain at one end issuitably attached to the lower end of a pipe, 0, and after passing upand around the pulley a it extends down through the roof of thedwelling, and is connected to a suitable windlass,D, supported andsecured to one of the floors of the dwelling. A pipe, E, is arranged tomove within the pipe U, and has connected to its lower end a chain orcord, 0, which passes up and around a pulley, d, fastened to the upperend of the pipe (3, and thence down to the stationary pipe B,

where it is secured in any suitable manner to said pipe. .The uppersection of pipe E has connected to it a suit-able cowl, F, whichoperates in the usual manner for conducting air to the pipes. The pipesB O E, which may be increased in numbers as found desirable, are ofvarying diameters, so that they will lit in one another, as shown inFig. 2. When it is desired to extend the pipes G E at the requiredelevation the cord or chain b is wound upon the Windlass until the pipesare at a sufficient height, the ordinary pawl and ratchet usuallyemployed on windlasses preventing the cord or chain from unwinding. Thepipes O E by their own weight will close, as shown in Fig. 2, when thecord or chain b is left free to. unwind, thereby preventing their beinginjured by severe storms.

By taking the air from a high elevation it is much purer andconsequently healthier than it it were lower down or nearer the surfaceof the earth, where the atmosphere is vitiated or foul, resulting fromdecayed vegetation and marshy lands and other causes from which malarialfever usually originates, this being entirely avoided by extending thepipes to reach an atmosphere entirely pure.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

In a ventilator for dwellings, the combination, with the stationary pipeB, of the telescopic pipe-sections and means for elevating and loweringthem, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.-

WILLIS EZEKIEL MOORE.
